Why is the man calling?

W: Pam’s Carpet Shop. How may I help you?
M: Yes, I saw an ad about your special sale on the new "easy clean" carpets. I would like to check them out, but I forget your store’s exact location. Could you tell me how to get there from Emerson Street?
W: Sure, we’re at 110 Foster Street, just one mile up Broadway from Emerson. We’ll be closing for today in about 20 minutes, so you may want to wait until tomorrow to visit us. The sale lasts all week, by the way.
M: I’ll do that, then. That will also give me time to gather together some color samples to bring with me.
